Fusion of part or all of the eyelid margins is termed ankyloblepharon. This condition may be dominantly inherited. Treatment is surgical. In ankyloblepharon filiforme adnatum, a variant of ankyloblepharon, the margins of the upper and lower eyelids are joined by fine strands of tissue (Fig 17-5). This variant is seen in Hay-Wells syndrome (also known as ankyloblepharon–ectodermal dysplasia–clefting syndrome), a form of ectodermal dysplasia that includes cleft lip or palate. The eyelid adhesions in children with ankyloblepharon filiforme adnatum can often be easily separated in the office with blunt scissors and topical anesthesia.
